lMPRovEMENT. `IN LANTERNS.

Specification forming part of Letters Patent N o. 222,145, datedDecember 2, 1879; application filed November 23, 1878.

To all whom 'it may concern:

Be it known that We, WILLIAM E. MASON, of Ohicago,`Illinois, and JOHN F.MASON and EDWARD R. MASON, of Des Moines, Iowa, have invented anImproved Lantern, of which the following is a specification.

The object of our invention is to prevent lamps and lanterns from beingai'ected by the pressure of the outside air and wind which frequentlyinterrupt combustion, cause smoke, ickering, extinguishment, andaccident.

1t consists in forming, arranging, andcombining breaks or detlectors inthe air-passages and chambers used to conduct air and oxygen to theburners Aand combustionchambers of lamps and lanterns in such a mannerthat the air will move in a zigzag or serpentine line and in acontinuons steady 110W, as hereinafter f'ully set forth.

Our drawing is a longitudinal partial section of a lantern,and-illustrates the construction and operation of our completeinvention.

a a represent the cylindrical body of a lantern. Itis made of sheetmetal, and may vary in size and conguration as desired. It has a Haringflange, b b, at its lower portion, which forms a broad base, upon whichthe complete lantern may rest. Perforations in this ilange allow air topass from the outside to the interior when the lantern rests upon atable or other solid surface. y

cis an oil-chamber, fixed in the inside of the body a a in any suitableway. It may be filled through the induction-port and tube d that extendsabove the top plate of the body a a.

e is the neck of the oil-chamber and vessel c, that supports the burnerand incloses the wick that extends from the burner to the oil.

fis a, burner, which may vary in form. g is a perforated diaphragmsurrounding the burner. h is the top plate of the body a a. It has aneck, t' t', corresponding with the neck e of the oilchamber, which necke it incluses in such a manner as to produce an annular airchamber'andconduit leading from below the top plate, h, to the top of the burnerand the burning wick 7c. i y

l t are circular rims xed to the under side of theixed plate 7L, andrepresent a graduated series of wind breaks or deflectors in a verticali position, to affect the air moving at right an gles thereto.

mm are correspondin g rims xed on top of the oilchamber, to extendupward between the depending rims `l Z in such a manner that each one ofthe deectors Zand m will act as a break in regulating the How of airthat must produce perfect combustion, and a good, safe,

and steady lightis the advantageous result.

n n is an annular chamber surrounding the oil-reservoir c. It has aseries of perforations, l 2 3 4, at its lower end, through which air isadmitted to be conducted upward toward the burner.

r r represent a series of delectors corresponding with the deectors mand l, xed in a horizontalposition against the inside of the body a. a.s s are corresponding,` deilectors, fixed against the outside of theoil-chamber c. These horizontal breaks r s in the vertical annularconduit n n may be used independently to accomplish, in some degree, theresults contemplated by combining them with the vertical breaks m l inthe horizontal conduit formed over the top of the oil-chamber c, tothereblsr lengthen the serpentine passage-way that conducts air fromVthe outside of the lantern to the burner, to produce perfect combustionand a safe and steady light by preventing an irregular pressure of thecontinuous air-current required to feed the flame at the top of the wick7c, and to keep every portion of the metal below the burner cool.

is an auxiliary vertical tubular conduit passing through the oil-chamberc, to connect with the air-passage surrounding the burner. It-,hasbreaks y and z, corresponding with the breaks o" and s in the annularconduitn n, and one or more of these tubes as may be used .in

'lieu of the annular conduit, or in combination therewith, to supply theamount of air re quired, and to suit the different forms, sizes, andcapacities of the lamps and lanterns that may be made by adapting ourinvention to all the practical purposes for which lamps and lanterns arerequire Any suitable and artistic formof lamp or lantern may be thusprovided with one or more conduits, that will convey air in a continuousserpentine and steady stream from the outside to the burner, to producean economical, satisfactory, and safe illuminator that can beadvantageously used out of doors in a Wind as well as in a house.

. when the continuous-waved plate is used as a deilector in a verticalposition, it forms a seriesof pockets into which the air enters and thenpasses downward and out of thc pockets before it ascends to feed thedame; and when it is used in a horizontal position it is simply anuneven partition'that divides the air-chamber into tWo series ot' radialpassage-Ways, to conduct the air through numerous and distinct conduitsfrom the outside toward the burner inthe center.

Our series of independent and xed defiectors do not divide lthe volumeof air admitted into the chambers or passage-Ways, but simply deiiect itabruptly at intervals to resist outside pressure, and to cause acontinuons steady flow, as required to produce a uniform and steadylight.

We claiml. In a lamp or lantern, a horizontal airpassage having a seriesof independent and fixed wind breaks or detlectors, m and Z, standing inopposite Ways from opposite sides ofthe top and bottom Walls,substantially as shown and described, to produce a zigzag or serpentinemotion of the air, as set forth, for the purpose specified.

2. The annular chamber and conduit an, having the air breaks theopposite walls and defiectors fr s fixed to of said chamber,substantially as shown and described, for the purposes specified. f 3.The tubular conduit having the breaks and detlectors y and z,substantially as shown and described, for the purposes specified.

4. The body a a, having the fixed top h, neck t' fi, and Wind-breaks ll,in combination with the oil-reservoir c, having a tube or neck, e, tosupport a burner and Wind-breaks m m, substantially as shown anddescribed, for the purposes specified.

5. The combination of the body a a., having top h i i, vertical breaks Zl, horizontal breaks r r and perforations l 2 3 4, With theoil-reservoir c, having top e and breaks s s, substantially as and forthe purposes set forth 6. The body a a, having a perforated ange,

b b, a top, h i t', perforations l 2 3 4, vertical breaks Z l, andhorizontal breaks r t', the oilreservoir c, having a neck, e, verticalbreaks m m, and horizontal breaks s s, when arranged and combined in alamp or lantern, substantially as shown and described, to operate in themanner set forth.

7. The body a a, having a top, h i t', and vertical breaks L l, theoil-reservoir c, having a top, e, vertical breaks m on, and the conduitx, having breaks y and z, when arranged and combined in a lamp orlantern substantially as shown and described, to operate in the mannerset forth.

8. The body u. a, having a top, hi i, and breaks l l and r r, andperforations 1 2 3 4, the oil-vessel c, having top c and breaks m m ands s, and the tube x, having breaks y and z, when arranged and combinedin an illuminator, substantially as shown and described, to operate inthe manner and for the purposes specified.
